To improve the social and economic position of the disabled people and secure their human rights, an integrated society should be buill. To build such a society, an adequate access should be provided to the movement or in using buildings or facilities. The inconveniences from social life on the part of the disabled people might not result from their impairment or disability, but from physical and social barriers in the environment surrounding them. Therefore, it is necessary to reconstruct entire systems of the society as a disabled people-friendly structure in order to remove those barriers, make them stand their own feet in our communities and freely participate in the social activities. This will eventually lead to build a society in which all people including the disabled people can use those facilities in a more convenient way. It is almost impossible for the disabled people to safely and conveniently access to and use facilities and equipments and freely move to their desired places, without any help from others in Korea. Even though, there are currently many disabled people-related convenience facilities, they have been independently built without a connection with other facilities and buildings, thus not greatly useful. Even when convenience facilities have been built, mostly they are superficially set up; therefore, in many cases, the disabled peOple cannot use those facilities. In this. research, I tried a new concept of mobile wheelchair lift design, which the disabled people can operate without restrictions, when using the public facilities. The key to this research was to develop the existing import-oriented simple functional products to a new system with functional safety and high quality orientation. Also, this research aimed at bringing an. import substitution effect, as well as preempting the mobile wheelchair lift market by advancing into overseas markets through application of new image designs in the field of disabled people aid equipments.

Car-sharing is a representative model of the sharing economy, and it is a service that rents or uses a car for the necessary time without owning a car. This industry is growing due to various factors such as technological advances, increasing awareness of environmental protection, and increasing demand for solving traffic congestion problems in cities. Accordingly, there is a need for a strategic approach for companies providing car-sharing services to respond quickly to market changes in order to expand market share and differentiate services. Accordingly, this study conducted a case study on open innovation activities between Gongcar and existing rental car companies, focusing on the research question "What effects do open innovation activities between car-sharing companies and existing rental car companies cause?" As a result of the study, it was confirmed that Gongcar have (1) the ability to actively respond to market fluctuations by establishing a flexible vehicle supply chain based on demand, (2) have significantly reduced growth capital expenditure (Growth Capex), and both cafe and rental car companies have (3) performed successful open innovation by improving key KPI indicators and recording financial performance. This study reveals how open innovation acts as a key business growth engine in the car-sharing industry, and its significance is found in that it empirically confirmed the successful implementation conditions of open innovation based on resource dependence theory.

The market for NAND flash-based storage devices has grown significantly as they rapidly replace traditional disk-based storage devices. Heterogeneous NAND flash-based storage devices using both multi-level cell (MLC) and single-level cell (SLC) NAND flash memories are also actively researched since both types of memories complement each other. Heterogeneous NAND flash-based storage devices suffer from the overheads incurred by migration from SLC to MLC and garbage collection of SLC. This paper proposes a new flash translation layer (FTL) for heterogeneous NAND flash-based storage devices to reduce the overheads by utilizing SLC efficiently. The proposed FTL analyzes the access patterns of logical blocks and selects and stores only logical blocks expected to bring performance improvement in SLC. The experimental results show that the total execution time of heterogeneous NAND flash-based storage devices with our proposed FTL scheme is 35% shorter than that with the previously proposed best FTL scheme.

Computer performance and the development of computer appliances of today have adopted a new shape of concept, "ubiquitous computing." Thus, users can readily obtain access to abundant information as they can utilize the wireless network taking advantage of the ubiquitous concept, which allows usage inhibited by neither time nor location. In this process, the supply and feedback of information tends to be made real in the form of "interactive agent". This interactive agent with the application of artificial intelligence can enhance the reliability of information using friendly characters, and is used as a tool to grasp the intention! and behavior patterns of the users. This paper will take a look at the concept and the definition of the intelligent agent with "added characteristic", and furthermore investigate the potential and the scope of its development analyzing its features and comparing the examples of the domestic market that pursues to generate profits with it.

지속적으로 변화하는 무역관습의 흐름은 결제관습에 있어서도 새로운 변화를 초래하고 있는데 최근의 국제결제시스템중 가장 두드러진 변화는 전자적 방법에 의한 결제시스템의 대두이다. TradeCard는 이러한 전자결제시스템으로서 가장 대표적인 예로서 1994년 처음 사업이 시작된 이후 10년도 되지 않아 새로운 무역결제관습으로 정착되기 위한 상업적 활동에 나서고 있다. 본 논문은 이러한 TradeCard의 상업적 활동이 과연 순조롭게 추진되어 신용장을 비롯한 기존의 무역결제시스템에 추가 또는 대체되는 새로운 무역관습이 탄생할 수 있을지를 검토하고 있다. 이를 위해 본 논문은 먼저 TradeCard가 갖고 있는 특징을 몇 가지로 분류하여 살펴보았다. 즉, 무역절차의 전자화 과정에서 기능적 접근방법을 채택하였다는 점, 타 기관이나 조직과의 활발한 제휴, 비용과 시간을 절감시킬 수 있는 방법의 제시 등이 그것이다. 이러한 특징을 통해 TradeCard는 새로운 무역관습으로 자리잡을 수 있는 충분한 가능성을 갖고 있다는 것이 논자의 생각이다. 그러나 다음의 몇 가지 문제점 역시 갖고 있기 때문에 이를 해결하는 것이 그러한 가능성의 전제조건이 된다. 첫째, TradeCard를 통한 거래의 법적 안정성 확보이다. 이는 모든 전자거래가 공통으로 갖는 문제점이지만 TradeCard의 경우 거래조건의 이행여부에 대한 전자적 판단이라는 요소를 지니고 있어 이를 어떻게 법적으로 수용할 것인가의 문제가 제기된다. 둘째, TradeCard를 통한 거래에서 발생되는 피해에 대한 구제방법의 제시이다. 이는 아마도 보험을 통해서 해결할 수 있으리라 생각되지만 현재 TradeCard는 이부분에 대한 명확한 입장이 명시되지 않은 것 같다. 셋째, 국제적 전자거래를 안전하게 할 수 있는 방안으로 전자서명의 활용이 절실한데 이에 대한 상호인정의 해결이 필요하다는 점이다. 물론 이는 TradeCard의 역할이라기 보다는 우리 정부를 비롯한 각국의 정부당국의 몫이다. 그러나 이러한 모든 문제는 결국 얼마나 빨리 많은 사용자를 확보하여 시장의 힘을 통해 국제상관습으로 정착시킬 수 있는가의 문제로 귀착된다고 본다. 따라서 TradeCard는 처렴한 요금체계 및 사용자에 대한 인센티브의 제공 등을 통해 조기에 다수 사용자를 확보하는 것이 시급한 것으로 생각한다.

Home network providers have many worries about providing home network services with an expandable, reliable, flexible and low-cost structure according to the expanding market environment. The existing client-server system has various problems such as complexity and high costs in providing home network services. In this paper we propose the P2P-SIP structure. P2P communication terminal supporting access of distributed resources provides functions which the existing SIP-based network devices have. Because diverse terminals in a home network access through networks, also, partitioning network domains with home gateways to manage, and applying the network-based PMIPv6(Proxy Mobile IPv6) technology considering mobility of terminals would help to have a more efficient home network structure. Especially, the proposed P2P-SIP structure proves itself as a very efficient structure to have an outstanding expandability among different home networks in a region, and to reduce maintenance costs.

Conventional design producing systems using the Internet are largely classified into two groups: a basic type in which an operator of a design producing site receives an order for manufacture of a design from a purchaser, produces the design based on the content of the received order, and delivers the produced design to the purchaser; and a type in which a purchaser inspects given designs and select one of them for purchasing. Such conventional design producing systems have following problems. Firstly, receiving an order over the internet and delivering a produced design to a purchaser has nearly the same procedure as a conventional logo design procedure with the sole exception that an order can be received through the Internet. Therefore, the production of a design still costs a great deal and takes much time. Secondly, inspecting given designs, selecting one and producing the selected design is like simply selecting a picture, and thus a purchaser is not allowed to modify a design. To solve the above problems, it is an object of the present a new solution to provide a self-design producing system and method using network, in which a purchaser searches a design database for a design suitable for the purchaser's company, determines a design database by modifying design conditions, and makes an order for manufacture of a product to which the determined design is applied, through the Internet.
